Wedding anniversary cake

This a cake I made for a 10th wedding anniversary. The client showed me a picture of a similar 5-tier black and white cake, so the idea is not totally mine. We did make the photos in colour, and scaled it down to only 3 tiers, since she was not expecting so many guests. The balls are made from fondant and dusted with pearl lustre, and the cake is vanilla with strawberry filling, covered in fondant and with the edible photos on.
